Title: Voltage generation circuit
Inventor: DOMINIKU SABUINIAKU
IPC: G11C8/00
Filed: 1994-07-15
Abstract: PURPOSE: To reduce loss power by providing a second comparator comparing an output voltage with a second threshold value voltage and switching on/off a first comparator device. CONSTITUTION: The comparators 6, 7 generate a logical H level on their output ends 9, 10 when the voltages to be compared are placed on the downside of respective comparison threshold values, and generate a logical L level when the voltages to be compared are placed on the upperside of the comparison threshold values. Then, a signal C on the output end of the comparator 7 is reset to the level. Thus, components in a circuit part are dimensioned for a lower operation voltage, and the loss power is reduced further.

Title: Apparatus for detecting corrosion condition of bottom plate of pool
Inventor: MAEDA HARUO
IPC: G01B7/06
Filed: 1989-07-19
Abstract: PURPOSE:To prevent water leaking accident beforehand by moving the probe of an eddy current flaw detector along the bottom plate of a pool, and measuring the thickness of the bottom plate. CONSTITUTION:A probe 12 of a main body of an eddy current flaw detector 11 is arranged so as to face a pool bottom plate 3. A current is conducted through a first coil 14. Eddy current is made to flow through a metal plate 3a of the bottom plate 3 by the generated magnetic field. The effect of the magnetic field generated by the current is imparted to the induced current which flows through a second coil 15. The thickness of the plate 5a is measured based on the change in phase angles of the currents flowing through both coils 14 and 15. The probe 12 is moved along the bottom plate 3 with a self-propelling device 17. The corroded state of the plate 3a is detected based on the position data obtained with the position detecting means of a control part 19 and the thickness data of the plate 3a. The corrosion can be found before a through-hole 5 is formed in the plate 3a beneath a lining layer 3b and water leaking accident occurs. The part of the corrosion 4 can be repaired. Thus, the occurrence of the water leaking accident can be prevented.
